“Genius tech­nol­o­gy” which auto­mat­i­cal­ly cre­ates playlists from songs in your music library that go great togeth­er, with just one click.

UI/UX improve­ments with the help of the accelerom­e­ter. This allows it to behave like the iPhone/iPod Touch between switch­ing from Por­trait to Land­scape modes.

Improved 24 hours of music play­back or four hours of video play­back.

I just won­der if its still nec­es­sary to buy the Nike+ piece since this new Nano now have an accelerom­e­ter built-in. If any, they should mod­i­fy the Nike+ piece to work with an iPod 1GB+ Shuf­fle; which will be tempt­ing for me to buy and use when run­ning. Bet­ter yet, just a stand­alone Nike+ piece that can sync on its own to the Nike+ site.
